You could ditch tactics in favour of Speed - i too love SJ too much to lose and so sadly tactics was dropped from my build 
Golden-Phoenix - Lvl 50 Fire/Fire Tank
Oodja Nikabolokov - Lvl 50 SS/WP Brute
Baby-Phoenix - Lvl 50 Peacebringer
How much wood would a woodchuck chuck if a woodchuck could Chuck Norris?
It sounds like your build isnt really made for straight up combat, alot of people use SS+SJ as movement for pvp so they can easily move around and keep distance from their target when fighting and also cause its fast :P. I think if you're going to be laying mines then tp foe onto them and finishing them with your primary attacks, SJ won't really be needed. You should be ok with Teleport as virtical movement it is kinda fast as a travel power but just annoying. Set up the bind that lets you hold a key and click where you want to Teleport and it should make things easier.
p.s sorry i dont know the bind lol :P
I used to have a similar style on my ice/dev. I went for Speed (Hasten/SS), Fitness (Hurdle/Health/Stamina), Leadership (Assault/Tactics) and Teleport (TP Foe/Teleport). It worked ace in Siren's Call. 
Ty Globey + all... Think that I will change it about and respec Donna Cryonix into TP + speed. What IO sets would be nice in Trip mine??
Or I may start a new /dev quite fancy a Sonic for the ranged stun + -res ...
Anyone got any thoughts on the what would be a nice change,,, I have Fire/Dev + Ice/Dev already.
Sonic always been a pain due to Rooting but without SJ dont think that would be an issue again.

Post 2 months too late, you probably got it binded by now, but oh well :P
The bind is;
/bind lshift+lbutton "$$powexec_name teleport"
This will make it so you hold shift, click and you'll me whizzed away thinkin; OMGWTF I LOOVE TIHS BIND LULZ
Well maybe not to that extreme, but yeah it works well.
@Lukas
Okay I would like power choice help... Slotting doesnt matter I can work that our later.
Thematically I am thinking about a Sirens Call Demolition Expert, Bombs, explosions etc etc.
So far I am leaning towards Archery/Devives for Trip mines and Explosive Arrow etc.
Main prob is I want Hasten as mine placing is a slow and tedious business. However the max of 4 pool powers is a pain in the *ss.
Stamina / travel / tactics / tpFoe - means no room for Speed.
I have been thinking about taking SuperSpeed as a travel and TP for vertical momement, but my usual SuperJump would be sorely missed.
Suggestions please.
