I use Satellite City Special T thick CA glue and it blends ok, although not as good a smooth on. It is strong enough for the job though, last fall I just finished a 60 lb bow and was shooting it and had a nock break and I basically dry fired the bow, ouch. The bow flew out of my hand and the tip overlays flew off and hit the wall, after further inspection the glue line was good, the store energy had to go somewhere and the actionwood actually tore but the glue didn't fail. I've used the glue ever since on tips and riser overlays.
I think smooth on is the best there is but I'm not that patient so I'll keep using the special t.
