are sportmaster shorties better than imco shorties for a cat, trying to figure out which is best, heard sportmaster are better for cats and imcos work better on a v-hull, any one got some feed back, don't want to get the wrong ones

I have a imco -2 getting on plane is not the best but once it is there no problems. I believe imco's are faster than the sportmasters do to the long skeg, but im no expert
