That valve ^^^ sounds like a waste of time, along with the forge split r. (i used to have one) i wouldn't be atall worried about buying the Forge look-a-like valve as they are all the bloody same!!! I have stripped down a forge 007p and one like you have mentioned, a blind man would be pleased to see the difference.
If you want to get bent over for a logo then fair game!
there is a huge difference. forge offer a lifetime guarentee. its been developed.
where do you get the servicing kits from for the copies? beefed up springs etc.
id never feel shafted buying from a company that is continuosly testing and developing their kit. even if the copy was 100% ...if we all bought it, forge would vanish and then theres nothing to copy and no better kit being developed.
