comparatively you'll feel like your riding a smaller bike alltogether. Though the Seat tube angle is 70 on the opsis compared to 73 on the wells 2. Chainstay is going to be shorter by about .4" which will make back wheel stuff feel a little twitchier. In all I say if your comfortable riding what you have now, then stick with it. If you want to try something a little more responsive then go for the wells because at 180 bucks its not a major cost. *I consider anything above 200 getting major*
You've got a beginner frame that technically is supposed to handle flat at a beginner range with slacker angles that feel more relaxed. Going to something like the wells lets you fine tune what you already know and lets you learn finer points like pvoting the frame around or learning g-turns.
my opinion, what the hell, go for it.
