So will i be able to texture and mat the big main piece without any strecthes if i make the UV carefully? Will this mesh let me do the UV map without any problems?

The thing with the smaller front ring mesh, is that i modelled it in 1 piece and had to make some corrections explained here https://simplymaya.com/forum/showthread.php?t=37048 when i take the edges out to get quads i get pinching at the corners which dont look good. Maybe i should have modelled inner pieces that gives the gear look seperately. But since its 1 piece i have decided to leave the triangles. Do you thing its a major problem?
