Spare ball -- same weight or lighter?

thanks for the replies
its great to here others views

since I throw my resin balls at spares, I've developed a second timing for spares. When I had a plastic ball, I threw it using my resin ball spare timing, open straight wrist, with a quicker approach pace.
Even with a 14 year layoff, it all came back, and I'm firing at spares with my HyRoad with good success. For the upcoming summer leagues I'm confident I'm ok not having a plastic spare ball. But my goal is to get back on the local ABT, and bowl other tourneys by the end of the year. And for those I do see a definite need for plastic.

99.99% of the top bowlers in the world use plastic spare balls. They do it for a reason, and it's not because they just want to lug around another bowling ball. Bowling on a house shot, with its built in friction on the outside makes a spare ball just as important as it is on a tournament shot.

I use the same weight plastic spare ball. I used to use the same ball for spares but is much easier with plastic and don't need to speed the ball up on corner spares. I hit the ball pretty hard and had to flatten my wrist out on spares and now with the plastic spare ball don't need to. I would keep the same weight ball for spares. Steve

I never had an issue switching from 16 to 15 pounds. But going from 16 to 14 pounds wouldn't be a good idea, timing wise. Using a plastic ball or urethane of the same weight will work as a spare ball.

I tried using my old Xxcel after switching to a 15 pound Bad Intentions and couldn't do it. Ended up giving away the Xxcel to a friend since it was going to be a paperweight.

There is no point in adding additional variables to your game use the same weight equipment for everything. Some people are more aware of differences than others but in my opinion even if you think it doesn't effect you it probably does.
