Cevelo R3 vs. Isaac Sonic

[nirism]

Could someone write + and - to either framesets ?
The use is for racing only and not for training or daily usage.
Thanks

Do a search on this forum and you'll find my experience with Sonic (Impulse). Not good.
Plus, and I could be wrong, but I'm pretty sure I read that Isaac went out of business?? Not sure, you can probably find something on the web..
