Hi mate welcome back

I would say the Cometa 220 as Ive been pleasantly surprised by the quality of these Cometas and a lifetime warranty from the importer, the 100 is a good youth gun set at 6ftlb and is easy to use with super light cocking, the 220 is a better choice if your thinking of adult usage and an adjustable trigger.

Just enjoy whatever you get him, happy days


Chris
