agree with above, keep it simple. im not keen on these bullet leads positioned up the leader as not only do they make the trace swing in the air in the cast but i can imagine that they will also hamper the fight of the fish, the lead will also pose an issue of getting snagged. using a lead up the line is moreso for when you wish to be able to cast a light-weight SP but i dont see them necessary, if you wish to cast a lighter SP then downsize your rod and line.
I just prefer using weighted SPs or leadheads and am a big fan of Sidewinder lures (the bigger they are then you effectively eliminate catching the smaller fellas, whichever you prefer). Sidewinders move brilliantly in the water and have caught me a lot of fish, but i am sure that there is a lot of weighted SPs out there that will compare just as well - beware of all the bling!
also agree with above, if you are snagging a lot and loosing stuff then up the strength of your line. i reckon that weighted SPs do actually snag less with the hook facing up, but only to a certain extent. if you keep snagging then practice judging your depths better i.e. keep the lure close to the weed but out of the weed at all times, try different weights of lure if need be, or a faster or slower retrieve. if you keep snagging then move along a little. if you arent getting pollack then try somewhere else.
big pollack like a very slow retrieve and dawn and dusk are always best. these fish can make some initial dives for the kelp as soon as they know that they are hooked! so watch this. if you get a big one then be prepared to hold on!

have the drag set. if they do get into the kelp and get stuck then it sometimes works to completely loosen your line for a minute or so, they can actually work themselves free if you are lucky.
good luck. hope to see some pics..
