SMT Plus has a good selection of reflow pads but no wave patterns (7th 
edition). Their pattern book costs $300.00. I can recommend their "SMT 
Design Rules and Standards" book instead, for formulating wave patterns. I 
have heard many reservations about IPC's patterns from other designers so 
use caution. No matter what, trust no one completely. Do coupon tests for 
your processes.

Can anyone help:
We currently design predominantly single sided pcbs with surface
mount componets wave solded.
Our footprint designs are based on Siemens recommended sizes for
805,1206 & sot23.
We are about to review our footprint designs can any one recommend
from their past experieces some footprint designs.

With thanks
