I dunno, I can't understand your sentance, But if you are saying that your Nomad bottoms out, then thats not a frame issue. thats a matter of your suspension. Stiffer springs, more air preload, dial uo compression, whatever. Doesn't exactly call for a new frame. If, however, you find that the nomads geometry is too steep for DH/FR (not likely) or the frame isn't strong enough to hold up to the kind of riding you are doing or maybe you just want that extra tiny little inch and a half of travel then sure, get a new frame. But if you are worried about it bottoming out then there are some simple adjustments that wont cost you a thing.
note - the other side of this is that you may be expecting your bike to make up for a lack of riding grace on your part. It ain't gonna happen. If you are dropping to flat, or weighting and unweighting the bike at the wrong time or whatever, then the bike ain't the problem.
If you must buy a new frame, the Trany, Turner, and especially the Trigger are all good pics, so is the VP free. I'd only get the V10 if you planned on racing.
