Well, if you go int hybrid you'll need to know that build's heavily dependant on alchemy. IMO, if you go int hybrid S/S, you're gonna want your mag balance to be well into 90%~100% or you'll just be plain useless in pvp. With the S/S you got weaker dmgs already, but you have the better defense. With that you'll want your nukes to be doing some real damage along side your phy. attacks, which'll most likely be your Knock downs and stabs.
I have an int hybrid S/S character right now and I love it, but it's really heavily dependant on alchemy. Right now bare, my stats blow (109 phy. and 137 mag), which cause my balances to be messed. From my current lvl on I'm just pumping pure int the rest of way to cap. By the cap and with statted gear, I'll have my phy balance into 7x% and my mag balance at 100%. That'll leave my nukes doing some major dmg, and my phy. attacks will do some good dmg too. I'll also have near 2k more hp than a pure int (w/ heuksal passive).
If you want to go 1 Str: 2 Int, just go with spear. If you go with that build your nukes won't be as damaging as a high int hybrid or pure int, but your phy skills will cause some pain.
It all depends on what you want. I suggest trying out the two and deciding, if you have the time
Best of luck~
