Russdog,
I got back in bowling 2 yrs ago after taking 5 off. Had to "rebuild" the arsenal since all my old stuff was urethane (all 16lb.) Started with a Spike HPT (partial to Faball!), 16, then added several others, 3-D Maxxx, Truck,
Black 2001, all 16, until I got a 15 lb. 3-D Violet Pearl, which I thought was a 15 lb. 15oz (as advertised), but was actually 15.15 lb. I was pissed at first
but it turned out to be the best thing actually. I found absolutely no difference in hitting power from my 16's and my accuracy was better with the 15. Alot of people say that 15's will carry better than 16's because they deflect a bit more, but I don't know about that. I think it's all how you throw them. Recently added a Blade Solid (15) and a Blade Pearl (16) to the ever growing arsenal, and I can honestly say the one pound difference between the two is barely noticable. Why? Because my driller has done so many balls for me he's got my specs down pat! Each ball fits perfectly and my release coming out is effortless. I think that's MORE important than deciding between a 15 or 16. Get yourself a GOOD driller who knows your game! Personally if I was starting from scratch, I would probably go with 15lb exclusively, but if
you buy alot of your stuff online like I did, and you like to get the most for your buck, you'll see that sometimes the 16's can be had for alot less than the 15's. Hope this helps some.
