Since you like cyclone/syn gut; demo:
1. tecnifibre ruff code 17G poly/tecnifibre NRB2 16G multi
2. SigPro Tornado 17G poly/tecnifibre NRG2 16G multi
Another thought is using volkl syn gut 16g as the cross instead of the more expensive multi. I have used this a lot lately and it is a slick syn gut that will not stick - low friction coefficient.
I am currently using Tecnifibre NRG2 17G mains/Tecnifibre Ruff Code 17G cross and really like it. Have been using softer string in mains lately but played poly mains in past.
The Ruff code is also kind of slick feeling too which is good in my opinion.
