Never seen an enstom mustering...so that will tell you something.
try R-22 V H-300, now your talking
Short term cost a R-22, Long term cost go the H-300
R22 is faster ( so you get back to the pug quicker)
H-300 is fair more manuavable.( yes I know I cant spell)
Check out the post on Mike Keyden, with him flying a 300. and that will give you an idea of about 40% of what a 300 can and will do..
Ask any old mustering pilot that flew 300's back in the 80's... They a fantastic machine
