I would put it in the 100-ish range. The tongues will also soften up once you put 20 or so days on them too. I'm 165 lbs, grew up racing, and used to a semi-stiff boot and rocked a #6 tongue for two seasons, then switched to an orange #9 last year, which I found a bit too stiff. Now I'm on a #8 and it feels perfect. But that's me. You might really dig the #6.
