More Wave Wall thoughts.
In my opinion:
The taped problems on that wall and throughout the gym should not be altered in any way at present (unless of course a setter decides to slightly tweak a problem on his/her own creation).
Any alteration of the current array (at least til the undergrads return and the gym is up and running full-bore again), should be highly restrained, very circumspect and EXTREMELY limited (whether adding or switching holds; there shouldn't be any fewer holds on the wall than there are at present.) Best approach, indeed, may be to just leave the array "as is" -- or nearly so -- at any rate not to undertake any significant re-set (especially if it's being attempted by one person without significant input and group-consensus).
Details and points to ponder:
In the wake of the comp, the Wave array has seemed generally quite OK/ reasonably good/ fully adequate/ [pick your phrase] -- for the immediate present. Especially so since there is an adequate array of unobtrusive yet very positive holds sprinkled throughout. (These holds are *vital* in order to allow greater numbers of people to enjoy use of the wall, both in terms of *levels* of climber [beginner, intermediate, etc] and also in terms of MODES of preferred climbing [ie not merely extremely short super-power sequences, but also power-endurance and full-endurance modes]).
The ideal of a well-distributed array of different kind of holds within a given area of wall is indeed generally admirable, ***BUT*** a seductive, possibly misleading/mistaken strategy can come into play: A person aiming at improving the Wave array might notice that, for example, there are some small quite-positive holds grouped in the middle and upper-third of the wall. S/he might be tempted therefore to winnow out some of these holds without realizing that it can be important that many/most of these positives NEED to be in somewhat-near proximity to each other. Reason being: imagine a climber reaches far out to the right and grasps a very positive handhold; since these positive holds are smallish and are not 2-handed buckets for matching, another smallish positive hold is required to accomodate the left hand as it comes over (or perhaps crosses through -- but not too far through!).
