mid range tele options which is best?

Currently using K10D and istDS. Shoot mainly outdoor motorcycling stuff, some in the woods (shady), some in the open. Some indoor (supercross once a year). The old FA70-200 and new FAJ75-300 4-5.6 lenses obviously just aren't fast enough to get crisp pictures. usually get 1 or 2 out of 10 that are usable but not great. Have the DA*50-135 but haven't given it a shot yet (winter time).

What does everyone think is the next best optical choice for a little more reach?

1) Sigma 100-300 f4 (assuming they'll make another batch soon)
2) Sigma 70-200 f2.8 with Sigma 1.4 TC (coming in the next few months)
3) Pentax DA*60-250 f4 (summer 2008?)

I don't believe I need much more than 300mm, but since I haven't been very successful, maybe someone could convince me otherwise. I'm usually adjusting the zoom for the scenario, so I'm not sure how well I would do with the new 200 or 300 prime coming out. Maybe someone who shoots a lot of this action sports can help me with that.

If you get an answer, let me know as I have the same problem. Do I get the Pentax DA* 300mm f4 or Sigma 100-300mm f4 or Sigma 120-300mm f2.8?

After reading numerous reviews, I would go for Sigma 70-200 f2.8 and 1.4 tele converter. Since I've started with sigma 24-70 f2.8 EX DG HSM for Pentax I need some longer tele. I was seriously considering Pentax 50-135 f2.8 however, the focal range is slightly too short! BTW, please don't be discouraged by some negative oppinions on SIGMA lenses, concerning the front/back-focus zoom. I've sent my 24-70 for calibration and it turned out that my K10D body was simply miss calibrated. There was a focus issue on almost all lenses I've used/tested and -410 um correction of focusing system solved the problem! Good luck!
