I figure I've made comments on the form of others on this board, so thought it only fair that I expose myself to the same scrutiny. I already have my own thoughts on what I need to work on, but an extra (dozen) pair(s) of eyes never come in wrong.

get better equiptment

Drrev, thanks for the input. The reason I have the ball is for my own benefit, so I know which one I'm bowling with. And for the music, I blame youtube, when I made the video, it was fine, but there we are. I, primarily, do these videos for myself so that I can look at what I'm doing and decide if I want to change/solidify anything, and just thought I'd take the chance to get some other opinions. Thanks for the suggestion about walking towards target though, I generally don't play inside lines that well (I can do it ok, but like a lot of things would like to do it better) I think if I can focus on turning my body correctly then this will be an ok compromise. When I took that video I was having a torrid time with moving left on the approach, which may have exaggerated the effect you saw. I've discovered over time that walking straight is pretty fundamental to my game, so if I can focus on that correct body turn of hips and shoulders (and feet for that amtter) and still walk straight, then that'll help a lot, thanks.

Mike, Thanks for the constructive criticism, anything you'd suggest?

APheLion, Thanks for the compliment, I noticed the power step thing too, and hope to get practice in next week to work on it, I might be able to reduce the sideways movement (above) too.

Thanks everyone for your time, and input.

bass, thanks for the input.

My accuracy before the operation was very decent, it's not bad now, but could be better, not sure how much of this is down to lack of practice/bowling in general though. On the lane condition in the video, there's a pretty much zero chance of me playing straight up the boards which is incredibly frustrating as I want to practice it. The drift is the biggest problem when it comes to playing straight at the moment, as my feet go left, my hand-eye co-ordination take over to make me hit my mark, meaning my swing is no longer parallel with the lanes. I've got some ideas about how to sort this over the next few weeks, so fingers crossed I should get back on track.
It's been commented before by my coach that I lean forward a bit at approach, and I'm kind of old skool in trying to get the ball down early which feeds into this. I don't think it does me massive harm at the moment, and it's something I've pretty much always done (because it "feels" better I think) but it's something else I'm trying to play with to make myself more versatile.

Thanks again

get some new stuff ( venom would be good for you)from alex's new proshop
and you will score better if you play more inside at stirchley!!!! carrys better in the middle!!

with the way you bowl, the venom will give u a few options, as it goes very long with great backend motion, so you could either move very deep and play wide left and just cross the head pin with the ball storing all the energy to hit very hard, or play way out side like playing right down 3rd or 4th board
( like the line you was playing at the tourney in tamworth last season)with the balls lenth and you style would be a great all round ball for you,

and it hits harder than anything else u have!!! apart from the widow solid

I would guess the Widow Venom would be a good fit in the same spot as your Total Inferno(medium-heavy?) but with more of a skid/snap reaction which you don't have in that area.  Just a guess.  But personally, I'm not a fan of skid/snap reactions and if you're carrying with a ball you already have that can be used on the same condition why bother?  I'm not aware of what the Impulse or Classic Zones do but it seems like you're only missing a heavy oil ball if neither of those cover that.

As for your video, I admire your approach really, for the most part.  Your approach is pretty close to my ideal approach honestly.  I also do a 4-step but have quite a few things to work on before I'm anywhere near as consistent as that.  I don't think you bend forward too much.  If you think you do, I think it's okay to get back to a straighter position at release which you seem to do somewhat.  Overall, your form is pretty much intact and it's really minor things you could work on, so I think Absolute had the right idea of working on solidifying other parts of the game that you may need to use at certain times.

Your arm swing starts just a tad early and your feet seem to play almost a little catch up getting you to the foul line a nanosecond early.   delaying your swing could slow down your legs accelerating your swing to then create more power.

A comment above was that you decelerated your backswing.   That could be why.
