I've used the IF ALC for a year in the past and 5-ply all-wood blades for years as well, the HL5 is quite slow in my opinion, almost ALL+, whereas the W968 is a definite OFF- with some OFF gears as well.
You'd be able to offer great comparisons with the IF ALC then, as I've never used it.
Im not sure I agree with the speed assessment though. I used the YSE, which is more of an ALL/ALL+ blade, for 3 months with D09C on FH before switching to the HL5. I actually first tried the one you sold me, and I switched back and forth between the YSE and the HL5. My blocks immediately started to go off the table, and loops that would've gone into the net landed. The blocks were easy to adjust to, and I fell in love with the way it loops, that's why I ended up switching.
To me, the HL5 feels like an ALL/ALL+ blade in the short game as I had identical control with services/receives as the YSE, ALL+/OFF- blade with medium strength shots including blocking against heavy loops, then OFF/OFF+ in loop drives. When I loop drive the speed/spin/control is tremendous compared to the Viscaria which I compared head-to-head with over the next week, but in quick counters on both FH and BH it's a bit slower and mushier. Since I mostly win points with loop drives, many of which set up by the service/receive game, I chose the HL5.
