I have two, both Mahogany, one has a Bubinga top and P-90s.
The double F-hole is lighter, it also has a really really light colored mahogany. I've not weighed either guitar.
The single F-Hole thinline has some fat sound to it, but its sound is really huge all across the tonal spectrum without any icepick.

In my experience, the Thinline is the toughest Tele to get a good sound from. If you're doing mstly home recording and stuff it's no big deal. But if you'll be gigging the guitar in a live band, it's a different story. The really lightweight Thinlines tend to have little projection and often get lost in the mix. Not ALL of them mind you, but more of them suffer than not.
WTF!?!?!? My experience is way different from yours. In fact, I find Thinlines to sound better when at gig volume. When your loud, you've been playing hard, its hot, sweat is pouring down your arm, you can feel air pump out of the F hole and onto your forearm, "The Breathe of the Thinline" I call it. My assumption is that all the surface area, inside and out, absorbs the vibration from the sound in the air, and creates a small breeze that flows out of the guitar. All the added vibration in the wood has a tonal impact, naturally, since sound is vibration. IMHO, its always sounded sweeter, smoother, and notes just leap off the guitar. I've had my old brown thinline for 13 years now, its been my #1. And my first Warmoth had to be a thinline as well.
