50lb braid?  Plenty, more then you will likely need.

If it is the good stuff, with the dia of 12lb mono, it will take 550m.

I don't know if you have looked at the Shimano page. If not here is the link

I haven't tried a Spheros out, but from what I have seen they should cast well.
Whether you need a 12 foot rod will depend on where you are fishing - but I would think they would match up okay with that reel.

na i havnt had a look the spheros' on the shimano website 

cheers 

If it's GT's you don't want to be using a 12 foot rod , 9 foot max and something with BALLS as casting up to 200g dumbells and big GT's a 12 footer will kill ya .

JMHO , after tangling with some up there .

As MAv said a rod around 8-9ft and plenty of guts is what you want.

You can also do an upgrade on the spheros for about $30 I think, Ryan from Oceanside may be able to tell you more.

thanks for the tip 

what is the upgrade? 

ive got a spheros 1400, ive got 500m of 50lb braid, they cast really well, but yer i deffinently wouldnt use a 12 foot rod for gts. 8 foots about right

Yeh mate i have two spheros 14000's and they are one of the smoothest reels i have ever used. As far as catching big GT's on them... You are talking to someone that has had fun with the big buggers on more than one occasion. As far as the drag on them go.... replace the washes with carbon tech washes as soon as you get it. One of the first fish that i caught on the spheros was a 20 plus kg at Coral Bay.
I actually run 65lb braid on it and really happy with the set up. Im actually in the process of replacing a spool that a drunken mate lost and will be putting 50lb on it. For the price of them and for chasing GT's... I recommend them.. Check out some of the pics on the 2nd or 3rd page of Pilbara Pirates of the GT's.

Im pretty sure the upgrade is the extra bearing. But do the wash's. Carbon tech or carbon fibre.... one of the Guru's will know what im on about.

yeh 

thanks for the info aye

been upto coral bay/exmouth a few times now and have hooked onto some really big ones but none of ma reels had the line capacity or the guts to bring them in.

what type of rod i was looking at ugly sticks and shimanos range?? 

I use a 10-15kg Live Fibre on one of them and is a good all round set up for what i do mate.... I do have a few cheap rods around the 6-7ft mark that i have bought off Ebay that do the trick too mate.... Saratoga 10-15kg as well. Depends if your fishin from a boat too i guess. Your call.
