Trying to figure out what to buy makes my head hurt

. OK, I've looked at some threads here, and read some reviews of what my lbs has suggested for tires.
The lbs has suggested:
option #1: Bontrager Race Lite Hardcase 700x25 ($40 tire)
option #2: Serfas Seca 700x23 ($38 tire)
This is the first thing I have had to replace on my bike. Giant OCR1. My tires now are Kenda Kontender 700x26. I have a bulge in the front tire that the lbs said it's just wearing out. *knocks on wood* I have never had a flat to date. I don't know if it helps that I keep them pumped up to 120psi most every ride, or that I am a lighter rider low 120#s?
I read a pro to the Bontrager is that it's very punture resistant. Con: heavier, and maybe not so smooth???
I'm not sure which Seca this one is (thus I posted the price to help sort it out if you own it/ know it). The lbs said it would roll faster for me, and is a really nice tire.
I do have some stability issues due to health, but do ok on my 26 tire now. I carry the supplies for the flat, etc. but fear I would have a bike stupid attack trying to change it. Smoother/faster for the Seca sounds nice though... less work riding means more enjoyment, ya know? *sighs with migraine*
Any thoughts on which way to go?
