I can only give you my experience, and warn you to be carefull as the wrong choice may cost you a lot of cash and frustration from early on.
Remember as a newbie you will hit the bottom a lot, carbon wings will not take the abuse, and damaged wings will cavitate and chuck you off before you know what's happening, replacing them hurts just as much as a good fast face plant.
I Started off with the slingshot school set up on the special offer alien board, 3 alli masts, very robust wing and stabizer and all quite heavy, but hay ho, I never damaged anything and I hit the bottom countless times, yes it was a pain lugging it out long walking distances and back again but it did the job of getting me up and ready for the dream gear, but there was a sting in the tail of this decision.
The good points were as I mentioned, durability, which made the gear easy to sell on as it was undamaged, in fact I sold it on the first day I was able to foil both ways for a good distance on the tall mast. I lost about £200 on the full set up, good deal, I was happy.
I was now ready (or so I thought)for my dream board, a new super lightweight Moses with 91cm carbon mast, then reality hit me, It was like starting all over, I had a hard time getting up and foiling on such a lively advanced set up, it was so hard compared to my every so easy slingshot gear, and the carbon wings were so fragile, and I was so bad at keeping them off the bottom, I needed new wings within weeks, but would I change the way I approached the sport? Absolutely Not!
The Moses gear is so sexy to even look at I have a full length mast polished up and on show in my house, it's a work of art!
I now have the carbon t60 board and wish I had started out on it as it offers better pop up after touching down.
Where I sail I sometimes have to walk a long way to the water, the Lightweight carbon gear makes this so easy, resting the whole rig on my shoulder without a problem for a very long walk.
