if i recall correctly, Tornado masts are 31'
i sail a 5.5 with a 30' mast. i started with a H Tiger spin.. it fit ok but my pole was pretty high.

I now fly a T spin and my pole sits a little low and i have an inch of downward pre-bend in the pole.. and my spin luff is JUST barely tight enough..

I doubt you could rig it on an 29' stick.

I have sailed the P19,.. it was great.. i am sure you will enjoy it when you get it out.
