is .032 rosin core okay for chip install?

[carpe_01]

I'm clearing my weekend so i can finally install my DUO chip on my V4 PS2 (the laser is working fine) question, i know most guides suggest .25 rosin core solder...i've looked all over madison and can't find any .25. i have a tube of .032 rosin core, from radioshack. is that okay to use? i have a nice 15w/30w iron, but the tip is too large. i bought the 15w pencil iron from radioshack: http://www.radioshack.com/product.as...51&site=search
I have nice 30AWG kynar and 22AWG stranded wires, got a fiberglass pen and wire strippers, de-soldering braid, and everything else i need to do the install. i've soldered on computer mobos before, so i have an idea of what i'm doing.


thx,
