That said, because you're like me and string breakage is not a huge issue, I would recommend to put the multi in the mains. It will hold its tension longer and your string job will feel usable longer than if you put the poly in the mains.
As for particulars, I've had good luck with both X-1 and LWXP 17 gauge in the mains with the TF BlackCode 17 in the crosses.
Going with a 17 gauge string might help with getting a bit more bite on the ball with your serves and ground strokes. Plus the BlackCode is slightly textured and will help with that too.
Since you're used to a nylon string already putting the multi in the mains will give you more of a familiar feeling as opposed to the other way around.
Good luck and I hope my 2 cents were worth close to that.
Listen to this guy
Back in 2008, when I started testing and using natural gut and different polys (believ me, I've tested a few polys now: Luxilon Alu Power, Alu Power Spin, Alu Power Rough, Blackcode, SPPP, Red Code, Silverstring, Hyperion, Tornado, TurboTwist, Pro Hurricane, Pro Hurricane Tour, RPM Blast, probably forgot some) - I tried 2 hybrids in the same 2 racquets, one with poly in the mains, and nat gut in the crosses, the other with nat gut in the mains and poly in the crosses.
I actually like the one with Alu power mains and nat gut crosses almost as good as the reverse hybrid with nat gut in the mains, but that is because (in my view) no poly feels quite like Luxilon Alu Power for the first 3-4 hours, but then it starts to lose its nice playing characteristics and turns into just another dead poly.
But when you try both hybrids, you get to feel the difference between them.
If you're used to synth gut, go with nat gut mains and poly crosses.
I've settled with VS Team 17 natgut mains and Luxilon Alu Power Rough crosses now, as I feel this hybrid plays very well until I break if after 8-10 hours. The reverse hybrid began to feel dead within 5-6 hours, prior to me breaking it, and I prefer the feel of natural gut, so I kept the gut in the mains and the poly in the crosses and haven't looked back since that.
If you don't break strings, then the poly at some stage will start to drag the overall performance of the nat gut hybrid downwards - but it's subjective when and if you start to feel this in your hybrid.
Federer, Djokovic and Hewitt plays with nat gut mains and poly in the crosses.
Murray, Roddick and Henman plays with poly mains and nat gut crosses.
They change their strings after 1-2 hours, so if you want them to last longer and feel better, I would use the nat gut in the mains.
Even though the poly dies in the crosses, I don't feel it as much as if the poly was in the mains.
