What would be a fun addition?

Looking for some insight on what I should consider adding to my collection, convoy hosts only. Aside from 3x/4x models, What would fill a gap in my collection that I don’t have? I’m thinking of building a small flood oriented light:

S21E with XHP50.3 HI R70 (5000K) 45° TIR

For reference, as of now I have:

Nitecore p15

Thrunite archer mini

Thrunite t1s v2

Convoy c8+ OSRAM W1

Coming in the mail:

Convoy l21b OSRAM w1

Convoy m21b OP reflector SFT40

I appreciate any and all insight! Thank you
