Your Pings are "med/high" trajectory. In my opinion, "High" trajectory wedges with a spin factor that fits with your type of game and the balls you use are worth their weight in gold (and it's credits, not coins --- oh, how I wish it were coins, lol!).
Given that you are used to the 3.0 meter of your Pings (yes?), you would be good with the 1295 Vokeys, levels 78-80 (meter 3.5). No need for the the 1800-credit ones you refer to, unless you want a slower meter.
