Haven't seen the overall specs to see if they lightened the TS2 FW head, but the shaft and grips specs are comparable to the TS1 driver. There should be lightening of the head to compensate for the shaft/grip weight.

Unfortunately, being sinister (LH), they don't offer this to me. If the interchangeable head weight, shaft, and grip are the only differences, I could try this combo in my current TS-2 5W (18 degree) to try to compensate for my aging 915 7W (nla LH) and setting it to 19.5 degrees.

I have just purchased the TS2 15 degree and am left handed. I got the 40 gram Speeder shaft 1/2 inch shorter. Best 3 wood I have played. Thought my 910 was great but this is much better. Hitting it past my TS2 driver with Kuro Kage reg so am thinking of putting the 40 gram Speeder in the TS2 driver.

Where can I get a TS2 lightweight fairway?! Don’t seem to be available on the usual sites.

The new TS1 lightweight driver shaft is available in a TS2 fairway. If using a -4 weight in the head (TS2 Lightweight) it would match up well with someone that has a TS1 driver. You can special order this set up from any authorized Titleist dealer.
