sd, look at the hammerhead evolution 110cm. perfect all around gun for less than 300$.
you will get the loading down after a few times out. its all technique.
if you have the money riffe c3x, or riffe euro is an all around great gun.
Omer guns look cheaply made and brittle, they also shoot thin shaft i think 6.25mm. it is a POS.
Mako is definetly an option. i personally dont like them. the line release does not hold more than one wrap of mono.
my two cents.
