cant deciede, extended hedge trimmer

i cant deciede what extended hedge trimmer i want, the stihl hl75 or hl75k.
the hl75 has a 59" shaft and the hl75k has a 42" shaft.
what would be more convenient to use. i already have a ht75 pole pruner and an hs85 30" hedge trimmer. i want something in between i was leaning towards the 59" but am thinking the length may be too long.
what do you guys think??

 

I have an Echo that has served me well for like 8 or 9 years now...not sure how long it is though. Plus, it articulates 90 degrees as well.

 

i forgot to say that what ever one i get will have an articulating blade.

 

Any reason you can't buy the HL75 (42"), and put the head of it on the HT75 (which you own) when you want a longer reach?????
This way, you'll have both.................

 

well im pretty sure when u buy it, it comes with the trimmer attachment already on it, i dont think u can buy just the hl75k(which is the 42" model) without any attachment on it.
can you???

i think i just got what you were tryin to say...im a little slow. lol
my ht75 has the chain saw and hedge trimmer attachments for it already.
this new trimmer i get would be an inbetwen unit, another words inbetween the ht75 and hs85.
i was out side doing some measuring, and the hl75(52") will be 24" shorter then my ht75, which is pretty good, im kinda leaning that way.

 

I have the Echo with the art. head, but to be honest with you, I hardly ever move the head. The only time I do is when I need to get between the house and a shrub, I tilt the head 90 degrees. That is not often though.
