I'm sure you are referring to the ALF solid, and not the ALF hybrid. I have had the hybrid version for awhile now, and the reason I haven't picked up the solid is because I can't imagine it being more ball than the hybrid. It is MUCH stronger than I had planned on. My step down from the hybrid is actually a Lights Out, which by no means is a tame ball itself. But compared to the ALF hybrid, it is much cleaner, longer, and smoother on the back. Depending on how much the lanes have broken down, I'm 8-10 boards right with the Lights Out. I'd wager that the ALF solid would be a remarkable ball on fresh med-heavy if you don't want to have to open your angles up right away.
