no they are not 4 wrap its a number 4 ,they rate them by number in reference to casting weight full blown cast , not lobbing a bait out on a wobble stick ,
number 4 will cast 4ozs in any style of cast and can Handel a full blown pendulum cast ,
with most rods we see in Australia the rating is all over the place ,
the number 4 is rated 5 to 7 kgs and 4ozs to under stand this a bit more to cast a weight of 4 ozs with a power cast the rule of them is 1 ozs = 10 lbs in leader so 4 ozs you would be using at least 40 lbs leader with 5 to 6 wraps around the spool joined to the 5 to 7 kg main line
some may think its a soft rod as from what they are use to in rod ratings ,
if you were to get into top jap gear the rod are rated either by number's like 25.27,30,33,35,40.45,andothers with leters xxx , xx ,ax ,bx,cx.dx.ex.
with the letters ST after the code meaning its a blank
this is a shimano blank SC 435XXX ST
sc = surf casting
435 = 4.35mts length
xxx is power level, XXX is the top level
st = strip ,meaning blank as we know things
Daiwia 425 33 ST
425 = length
33 is power level of casting weight .
st = strip
Understanding these ratings can be hard
