In reply to garbage:
If you're new to fingerboarding, probably not much gain. I think I spent the best part of a month working out how best to use it, where my limits were, etc. Immediately after that I probably got the fastest improvement though! I'm sure I won't be the only person to suggest going down to the bouldering wall an extra session or two per week. You can probably get a 1 month pass to limit the cost, as long as you have the time.
