The skills required to bowl on a houseshot are not the same as sport shot.
A year ago I switched to bowling with no thumb. Practiced a lot (mostly on burned up houseshot with plastic or weak urethane) for 9 months and then joined 2 sport shot leagues in the summer. It was a steep learning curve, but I finished season averaging in 170's in both leagues, but more importantly, easily in the 180's by the end with huge improvement.
Then entered a 8 game house shot tournament.
I was ok for 2 games, and then after was a mess, has two games in the 140's while everyone else was over 200 for each game. The tournament winner averaged like 249.
What happened was I thought I could go in with my sport shot arsenal and make adjustments off that. That is mostly non-reactives (I think a better term than urethane) and keeping ball in front of me for control. And with my almost 400 rev rate and about 3 degrees of axis tilt, my Fever Pitch and Covert Tank can look like reactive the way they hook.
Good for 2 games. Then went over to next pair. Ball hooked significantly more. everyone else burned up the front. My non-reactive stuff wouldn't get through. Unless I moved deep inside. More than other people. Then too much oil. But then I would have had to been in front of ball return and lofting gutter - which I can't do as only been bowling this way for 1 year, so I can't get that deep when playing the right side lane.
I needed to bring reactive and move in deeper than everyone else, but didn't even take the right balls with me, b/c over the summer, I really didn't need reactive.
So I had 6 games on extreme under-over house shot all between 144 and 190.
As of now, there are some sport shot tournaments coming up. Honestly, I can enter those where like 200 avg or less, might make cut for match play, and even if I have a bad game I can make it up. I practiced all summer and different patterns and and no problem doing 180 plus. So I feel if I bowling good I have a chance.
On house shot tournament have to avg. 230 just to feel like keeping up with the pace while chucking the ball from 40th board out to 5.
I'm not bowling house shot anymore. I'm going to vote with my dollars. I'm not interested in bowling league, throwing some 220's or whatever I'd avg. I'd rather work on my game and learn how to compete in sport shot tournaments (which there are now much more of) and sport shot leagues in summer.
From a certain perspective am I abandoning house shot b/c my game isn't as good for it compared to others - well sort of. But I love sport shot bowling. It's fun and challenging and I need to learn different skills, play angles, learning lane adjustments.
House shot is just move left and chuck it right.
But getting to the point - is house shot a different skill than sport - yes.
Does that make one better than another? Is it more of an accomplishment to avg 210 and win on sport shot than win with 250 on house? I guess that is a matter of opinion.
ok, end of rant
