I think I may have misunderstood, but ATP hasn't been in San Diego for quite some time...foolishly.
Plus One is probably the best club on the field at MYF in terms of aircraft variety, though their membership fees are also the highest. I belonged to Sorbi (dunno if they're still in operation, but stay away if they are), then Consair (good rates, limited fleet).
The San Diego FSDO is pretty tough on everybody; there's one inspector who has a penchant for busting people moving aircraft around *by hand* without their nav lights on at night.
