Need some help to become a better infuser.

I always love to play as an infuse monk because it is very challenging. Everytime you save a spike you just feel so good!!

However, i believe i could much improve my infusing skill by helps from those adv. pvp monks in this forum. I would list out what i am doing and see if i am doing something wrong of should improve...

Here is my skills list, typical sb/infuse for HA build.

1. Kiss
2. Infuse
3. Spell Breaker
4. Healing Seed
5. Orison
6. Heal Party/ Holy Veil
7. Insipired Hex
8. Channeling

Basically if i am playing a spike team, i would do this:

1. Not casting anyother skill and prepare myself for infuse healing
2. Position myself so everyone are in my healing range
3. Put a SB on myself so i take less dmg from a spike
4. Pick up an enemy spiker as my target, so i can spot what he is casting and prepair my infuse heal.
5. While a spike come, i click onto the hp bar of their target, then pull a infuse.

Most of the time without any interrupt or delay, i can pull out my infuse in 1.2 ~1.8 sec.....i believe this might be not good enough for high end infusing and thats why i need some help to improve this!!

Currently i will click on the spiked targets hp bar from the party window....I have tried to setup up hotkeys for 1~7 ally but it seems not working well on me.

I also tune up the brightness of my monitor for HA since the map is so "dark" as sometimes i can spot the target on the map too......

I wonder if some adv. infuse monk actually click on the spike target "on the battle map"[on the person] instead of clicking him on the hp bar in party window??

It can be useful to watch the game, in most (all) spikes the spikers will turn towards there target, this is particularly useful against blood spike, if you stand behind a blood spiker and see him turn towards you, the spike takes so long to cast that you have time to spell breaker yourself before it hits.
