Dats, two things to consider if you do extend those RDIS200s:
1. An extension of 0.5 inch will increase swing weight of at least 10 points but maybe even 25, every frame is different. So according to TW, 326+10 isn't too bad but 326+25=351 would be a bit too much considering the extra length. Typically 27.5 frames with manageable swing weights are in the 330-340 range, otherwise they're too sluggish.
2. Check my comments on the last few posts in that balsa wood extension thread. Either use bass wood instead, using that method, or I have 3/8" balsa wood that you can cut and use it lengthwise against the grain for additional strength.
