Anyone ridden a Slingshot 99cm and Armstrong 2400?

This is a lot to think about and I've learned a ton. Thanks for all the insight. I really appreciate the multiple perspectives.

I'd echo staying on the 99 a bit longer. I spent about 10 sessions learning on the 84 before getting the Armstrong 1850 rig. I was glad to have the 84 prior to the 1850 and I still really love the ease of use and turning of the 1850 despite owning a few HA foils.  The 2400 is really a foil to use a few times as a complete beginner or heavy rider before stepping to an 1850 or smaller. I'd skip it and stay with the 99 until you feel dialled. I love the HA wings for fanging around and gliding but also appreciate the turning and ease of use of lower aspect wings.
