As most of you will know I am a tube guy. But I was getting frustrated with their poor performance in colder weather. I tried the .5 simpleshot bands and wow is that some fast shooting. My taper is 15x10 at a 7.5" cut length. Shooting ¼" it is very fast at 10m and 8mm steel is flat at 10m. When I shorten to 7" boy does 8mm fly fast. And ⅜" is flat at 10m, but slow and flat.
I shoot my 1632 tubes in the afternoon when it's warmer now with great success, but in the mornings I stick to the .5 SS bands which fly straight at low temperatures.
I used a 9/64" hole in my mini shooter and the .5 bands are tight and perform well with my mini shooter as well.
7.5" has a draw weight if 6.70 pounds and there 7" is 8.20 pounds.
I have found that the 7 1/2" cut length is plenty fast for my ¼" Steel and it has a nice light draw weight.
Yes still have my 1632 tubes just don't work well at all in the winter. I think the .5 for my 6 a.m. shooting and once the winter hits I'll definitely want to be outside instead of shooting into the laundry room.
