In reply to racodemisa:
It sounds like what you're saying is, although there are plenty of problems graded V2-V4 at the climbing wall, most of them are much easier than V2-4 and you're using your personal idea of what is which grade wise rather than the grades the walls give stuff which is throwing everyone off.
So I assume your frustration is partly at the overgrading of low-end problems at many walls and partly at the lack of problems which you deem to actually be V2-V4?
I'd agree many low-end problems indoors are over graded, I think it's because the V grade system was invented outdoors and designed to start at a reasonably high level already as bouldering at the time was only really done by fairly hardcore climbers either training for routes or seeking new challenges.
Indoors though problems start very easy for novices and easy warm-ups, so you'd be a bit stuck in grading 20% of the problems as they would mainly all fall at or below V0.
So walls naturally have just spread the lower end of V grades out a bit to suit the typical range of difficulties at a wall. i.e the easy circuit is V0-V1, the next one up is V2-4 etc even if in reality, outdoors they would be probably all come in as different shades of V0/1. Once you get back into harder grades the grades tend to balance out a bit, normally around V6 typically.
The solution to your problem though is quite simple, just don't give a sh!t about what 'grade' you're climbing indoors as they are basically meaningless and the problems won't exist in a few weeks anyway. Most of the places I climb indoors have broad grade bands to the point where it could be anything from V4 to V8+ so basically you just climb what you can climb and fall off what you can't. It'll soon become apparent which are hard and which aren't, you don't need a little bored with numbers on to tell you that.
So just go out and enjoy yourself and have a solid session, if you can flash it then it's too easy, if you can barely pull on then it's too hard and if you just about manage it after a few goes then you've found that sweet spot.
